Deciphering the Neurotoxic Effects of Karenia selliformis [PDF]

open access: yesToxins
Karenia selliformis is a globally recognized dinoflagellate associated with harmful algal blooms and massive fish kills along southern Chilean coasts. Its toxicity varies with environmental factors and genetic diversity. While K.

Evaluating Bias in Self-Reported Symptoms During a Cyanobacterial Algal Bloom [PDF]

open access: yesToxins
Algal blooms produced by cyanobacteria liberate microcystins and other toxins that create a public health hazard. During the 2018 bloom of Microcystis aeruginosa in Florida, USA, residential and recreational exposures were associated with an increased ...

Total Synthesis of Brevetoxin A [PDF]

open access: yesOrganic Letters, 2008
A total synthesis of brevetoxin A is reported. Two tetracyclic coupling partners, prepared from previously reported advanced fragments, were effectively united via a Horner—Wittig olefination. The resulting octacycle was progressed to substrates that were explored for reductive etherification, the success of which led to a penultimate tetraol ...

Detection of Brevetoxin in Human Plasma by ELISA. [PDF]

open access: yesJ Anal Toxicol, 2022
Abstract Florida red tides have become more common and persistent in and around the Gulf of Mexico. When in bloom, red tides can produce brevetoxins in high concentrations, leading to human exposures primarily through contaminated food and ocean spray.

Total Synthesis of Brevetoxin-B [PDF]

open access: yesJournal of the American Chemical Society, 2003
Brevetoxin-B (BTX-B), produced by the red tide organism, Gymnodium breve Davis, is the first member of marine polycyclic ethers to be structurally elucidated and one of the most potent neurotoxins. The structural feature is a trans-fused polycyclic ether ring system with 23 stereocenters.

Exposure to the Florida red tide dinoflagellate, Karenia brevis, and its associated brevetoxins induces ecophysiological and proteomic alterations in Porites astreoides. [PDF]

open access: yesPLoS ONE, 2020
As reef-building corals are increasingly being exposed to persistent threats that operate on both regional and global scales, there is a pressing need to better understand the complex processes that diminish coral populations. This study investigated the

Revisiting the Neuroblastoma Cell-Based Assay (CBA-N2a) for the Improved Detection of Marine Toxins Active on Voltage Gated Sodium Channels (VGSCs)

open access: yesToxins, 2020
The neuroblastoma cell-based assay (CBA-N2a) is widely used for the detection of marine biotoxins in seafood products, yet a consensus protocol is still lacking.

Synthesis of the A−F Fragment of the Pacific Ciguatoxin CTX3C by Iterative Ring‐Closing Metathesis and Tsuji–Trost Allylation

open access: yesChemistry – A European Journal, Volume 29, Issue 72, December 22, 2023., 2023
The fully functionalized A−F ring system of the Pacific ciguatoxin CTX3C suitable for coupling to the I−M fragment of the natural product, has been synthesized from a simple glucal derivative. A six‐step sequence that features ring‐closing metathesis and stereoselective palladium‐mediated allylation has been deployed in an iterative manner to construct
